Part 1:
pH = -log(4.5 x 10^-4) = -log(4.5) + 4 = 3.35
Therefore, the pH for [H3O+] = 4.5 x 10^-4 is 3.35.
Part 2:
pH = -log(0.00028) = -log(2.8 x 10^-4) = -log(2.8) + 4 = 3.55
Therefore, the pH for [H3O+] = 0.00028 M is 3.55.
pH = -log(4.5 x 10^-4) = -log(4.5) + 4 = 3.35
Therefore, the pH for [H3O+] = 4.5 x 10^-4 is 3.35.
Part 2:
pH = -log(0.00028) = -log(2.8 x 10^-4) = -log(2.8) + 4 = 3.55
Therefore, the pH for [H3O+] = 0.00028 M is 3.55.
